3.- Adjust the TV picture with our video patterns as it indicated in the instructions on this page.
2.- Download video patterns.
It is important that you download video patterns according to the resolution of your TV.
On the download page just press the arrow ⬇ and starts downloading video patterns on your computer. Unzip the folder, pass the folder as it is in USB memory. Then connect the memory in your Blu-ray player or game console and play the video patterns from section images or photographs.
Our video patterns are as JPEG images, we did it this way because the images have less compression that video files therefore they are much more accurate.
Video patterns with the BT.709 standard (for HDTVs and some TVs UHD)
Video patterns with standard BT.2020 (for TVs UHD)

3.- Adjust the TV picture with our video patterns.
All video patterns of this guide can help you understand the behavior of the video signals, as the TV handles the video signal and the way it is factory set.
For the best picture the TV can offer set the TV with all video test patterns, It is very simple! and you do not need to make adjustments with all video patterns, some are just to make sure everything is properly. Once we know what we have to do, adjust the TV picture will take very little time from 10 to 15 minutes but if you want to try all options and not ignore any assumptions it may take up to an hour to adjust the picture on the TV.
If you have no knowledge about how to adjust the TV picture you can get a much better picture of how came from factory and if all patterns play properly on your TV then the image will look as seen by professionals in the video industry.
01.- Cut & Sharpness.
With this pattern video we can see if the TV makes a cut in the image. For a full picture and the maximum resolution of your TV:
- Set the “Image Size” (in TV settings) until all lines and numbers are visible.
In the TV menu settings these settings are called: TV appearance, TV format, Screen Format, Image size, etc.
Numbered lines in the four corners of the image show the amount of image pixels that are cut, if there is a cut in the image.
If this does not solve the problem also modifies the video settings in the video player. These settings are called: TV appearance, TV format, Screen Format, Image size, etc.
Remember that in “Device Configuration↗︎”. are all common configurations of the most recognized brands.
It is possible to arrange the cut video image if we reproduce through a Blu-ray player or game console connected to the TV’s HDMI input, but probably you can not fix the image when playing video from the USB input, air video signal or any other input or TV applications.
Once you have solved the problem of image cropping, you can properly adjust the sharpness. Sharpness usually looks perfectly at a low level, Too Sharpness is not necessary or image saturates. In digital image signals of the video player is sent at full resolution, so we should not add more information than necessary.
- Adjust the Sharpness until no white blazes in the center lines of the image.
Lower or increase the level of sharpness until the lines and points in the center of the image is perfectly see. If you increase the sharpness too you can see shadows or glare White around the “rectangles” and the black lines, only adjust the sharpness until these blazes are not visible.
If you increase the values of Sharpness and do not appear gleams in the black lines or no apparent change in image just let Sharpness in a value of 25% or 50%. For example if the scale of the TV is 0 to 100 keep Sharpness 50. In some TV models there is no apparent change when an image is displayed on the TV but the change is very noticeable in moving images.
If the brightness is set too high the picture will look pale and the colors are muted, if the brightness is set too low the picture will look dark and we lose a lot of picture information.
- To properly adjust the Brightness only increase the level of brightness of the TV until all bars are visible and lower the brightness until the bar indicated as 1% is barely noticeable.
LCD TVs and LCD TVs with LED backlight (known simply as LED TVs) always have a residual brightness across the screen by the LCD panel, causing the black color look a little pale and not a “pure” black. You can do a little experiment, play the video Brightness pattern and observe the black background, raise the Brightness and then decreases the value gradually, It reaches the point where the black level of the TV can not be more black. Even if the brightness level completely down the black background will look a little pale.
In this video pattern is a white background and on it bars grayscale, this pattern video works to adjust the contrast properly on TV and it works to see color changes in the image.
- To properly adjust the contrast on your TV only increase the Contrast level with no gray bar disappears, the bar indicated as 99% should be barely noticeable (sometimes it may disappear) but all the bars between 75% to 98% should be visible.
Sometimes there are color changes in the image and the color white is not really White, These color changes are produced by the TV settings, the video signal produced by the video player or the way in which the TV interprets the video signal. By increasing or decreasing the contrast you may see changes in tone of the image, yellowish white, reddish, even orange, It is easy to perceive color changes with this pattern video, We can make color corrections using the “Contrast” pattern and “Color Scale” pattern but this will be seen later.
04.- Color Scale.
With this pattern video you can adjust the color on the TV without using measuring equipment or color filters. For best results Brightness and Contrast should be adjusted perfectly.
- To properly adjust the color on the TV increase or decrease the color until all blue bars are visible (only observe the blue bars). The bar indicated as 99% can be barely noticeable or may not be visible. Today it is not necessary to adjust the tint, only Color.
If you increase color too the image is saturated and the bars with the highest percentage were lost. Bars indicated as 99% may be barely noticeable or may not be visible.
How to adjust other color bars if there is a cut in them?
In some cases it is possible that the level of a specific color increase so that the TV picture look more striking in the store, It will be very easy to see if a color is saturated since that color bars disappear when properly adjust the color (with the blue bars) or even if we reduce even more the color level.
Once you have set the correct color level, where all the blue bars are visible, we decrease the value of “gain” in the options “White Balance” Tv; values “Saturation” or “value” if the TV has a Color Management System (C.M.S.).
Although our video patterns are very easy to use and explain in detail how to adjust the colors correctly, this step can be a bit tricky and is recommended for slightly more experienced users, if you set correctly color with blue bars but there is a cut in other colors and do not want to take chances with the following procedure it is best to leave it and continue with the other video patterns.
Here are some examples of menus where we can make changes to the gain of colors in different brands of TVs.
LG TVs color modification is performed in White Balance and Expert Control/Color System Maintenance.
SAMSUNG TVs color modification is performed on White Balance.
SHARP TVs color modification is performed in C.M.S.-Tone, C.M.S.-Saturation, C.M.S.-Value.
SONY TVs color modification is performed in the White Balance.
VIZIO TVs color modification is performed in color temperature.
If the color is set correctly and all the blue bars are visible but the red bars are cut by 90% only you have to reduce the value of Red Gain in the White Balance settings; reduce the “Saturation” or “value” if the TV has a C.M.S.
Optional: If the TV does not have advanced video options such as White Balance or C.M.S. Adjust Brightness, Contrast and Color as listed in this guide, then reduce the Contrast level until all the bars of all colors are visible on the video pattern Color Scale or at least most. Not recommended too decrease the contrast, only enough, remember that contrast is what gives the image brightness.
Finally, we make sure that we have done a good job. In the video pattern Color Scale all bars should be visible and the video pattern Contrast the White must be really White.
Example of the most common case:
All colors shown on TV are produced by the combination of all shades of color, if you can not see all percentages in the bars of all colors in the video pattern Color Scale will lose thousands of colors in the image as these color tones can not be combined with other color tones, simply canceled or replaced by an equivalent and those millions of colors that could produce the TV does not appreciate, making the final image is not faithful to the original image and lose color gradient in all colors.
05.- Color Bars Calibración HD.
This pattern video contains all previous pattern video and it serves to verify that everything is properly.
With this pattern of video can easily adjust the brightness, contrast, image ratio, color intensity and tint, and to adjust each color individually.
We made this video pattern as some TVs behave differently when there is a single video signal (for example only one brightness signal to adjust the brightness with the video pattern) and when we have all colors and contrasts in a single image, as happens regularly in an image of a film, TV series or video game.
With this video pattern is very easy to see if we have the right levels of Brightness, Contrast and Color when presented simultaneously in a single video image.
No need to use measuring equipment or color filters to know if something is not set correctly and solve it will be very easy.
Optional: In the lower right corner two rectangles are included (Blue on gray background and Magenta on cyan background), with these rectangles we can adjust the color and tint with color filters or by setting the TV picture on Blue only mode, do not need to set the color and tint in this way is only optional.
06.- Color Bars Calibración HD (Black).
This pattern video has the same function as the previous pattern video with the only difference being the black background. Some televisions and video players handle color signal differently when the color Black occupies most of the image, for example night scenes, horror movies where most of the scenes are dark, etc.
01.- Croma 4-4-4 & 4-2-2.
- Play the video pattern “Chroma 4-4-4 & 4-2-2” if you can see the three squares on the left side the TV can receive a signal 4:4:4.
This is the only pattern found in PNG therefore the Blu-ray player, Game console or TV must reproduce images in PNG in order to perform this step.
Sometimes a computer is connected to TV for professional work or play video games with high image quality. With the pattern “Croma 4-4-4 & 4-2-2” we will see if the TV is capable of receiving a signal 4:4:4 for use as a monitor or can play an excellent video quality.
If you want to connect a PC to the TV, so this work as a monitor for professional work you must first know if the TV can receive a signal 4:4:4. It is important to know the type of TV with that account, since the image could be very bad.
You need to know if your TV can receive a signal 4:2:0, 4:2:2 or 4:4:4, only then we can choose a suitable color space from the Blu-ray player or PC graphics card.
When playing the pattern “Croma 4-4-4 & 4-2-2” we have to be able to see three square magenta inside the rectangle indicated as 4:4:4.
If we can choose any of these options in the Blu-ray player, 4:2:2, 4:4:4, RGB, as output video signal then the first thing we must do is determine the type of signal that can accept the TV, usually just send a signal 4:2:2 but some TV sets can support a signal 4:4:4.
If your TV can not receive a signal 4:4:4 can not be used for professional jobs such as photo editing or video, screen colors will not be correct for this type of work, it will not be a great choice for PC gaming in high quality, but it will be great to watch movies from a Blu-ray, via streaming and video game consoles last generation.
Recall that the video content is compressed to be recorded on a Blu-ray or to be transmitted via streaming.
Usually the video is compressed in something called 4:2:0, but, to be played on a TV that video signal 4:2:0 should be converted to an RGB signal, for this, must first go through other processes. This is the string conversion:
4:2:0 —> 4:2:2 —> 4:4:4 —> RGB.
Video conversion can be performed by the Blu-ray player or the TV, but there will always be one that will do better.
In television there are no options to adjust the video signal, these configurations always do it from the video player or PC graphics card.
The advantage of having a TV that supports a video signal in 4:4:4 is that we can use this TV as a computer monitor or at least will look quite similar to a monitor.
Not enough to establish a video output 4:4:4 from our computer, It is also very important to choose a correct color space for the kind of work that we will perform, for example, for editing pictures we can set the color space Adobe RGB (1998), sRGB IEC61966-2.1 o BT.709 for photographs or images in internet. For your TV look like an Apple monitor choose iMac color space. To watch movies or editing movies in HD choose sRGB IEC61966-2.1 o BT.709, to watch movies in 4K or 4K video editing we choose BT.2020. These are color spaces most common but there are many more, we must choose the color space that best suits the work that we will do. For PC games we will see in the features or options the type of signal handling and the characteristics of the video card our computer.
If you have performed all steps of the Main Patterns you will not have to do anything with this pattern video just check that the image is displayed correctly.
In this video pattern we have two gradient bars, the top bar has no color correction and the bottom bar has color correction. By using the standard BT.709 (color space for HD content) It can generate a yellow tint in grayscale images (White and Black movies) but also alter the colors in color images.
White & Black films which have no color correction, White color will look a little yellow and gray-scale will not be gray, the pixels have tones, Red, Blue, Cyan, Magenta, etc. Some TVs have an option called White and Black and TVs that do not have this option it is recommended to fully lower the level of color when playing movies in Black and White to look at with a correct grayscale.
To not have to choose the option of White and Black or not having to completely reduce the color TV, you need to adjust all bars of all colors as explained in step “04.- color scale”.
To properly adjust color TV:
As mentioned above, it is advisable to adjust the tint that is generated by the color temperature or color space used as this also affects the color reproduction in color images. For the color reproduction is accurate or something close to that.
This pattern video only serves to verify that the levels of gray scale are correct, if the Brightness and Contrast are set correctly we will see each of the bars and if the color is established correctly no color cast appears in the image. This pattern also serve to observe if there is any fault in the panel backlight.
If the color tone in the picture it looks bad you need to adjust all bars of all colors with pattern video “04.- Color Scale.
These patterns video are just to verify that the TV is not making any cuts, we can see an image without distortion regardless of the format in which it was created video content and we will see in full resolution.
- Having done all the above steps these patterns video should be viewed without any deformation (straight lines and perfect circles) no strange colors must appear within the white lines, the background should be a gray background and there should be no cuts in the image.
Widescreen 16×9 (1,78:1).
For expert users or those who want to adjust the TV picture with measuring equipment you can use both video patterns are included in the section Advanced Patterns.
01.- Color and Tint.
02.- Colors 75%.
01.- Color and Tint.
- To properly adjust the color, with the TV in the Blue mode or looking through a color filter Blue, only increase or decrease the color intensity until the gray and blue rectangles are matched, then only you see a single rectangle, Blue.
Note: This pattern works correctly but to adjust the color recommend using the pattern of video “04.- Color Scale” since in some TVs, to adjust the color with this pattern using color filters or using the blue TV mode if we return to video pattern “04.- Color Scale”, some color bars are no longer visible.
- To properly adjust the tint, with the TV in the Blue mode or looking through the blue color filter, only adjust the value Tint to match the rectangles Magenta and Cyan, then only you see a single blue rectangle. With TVs today is not necessary to adjust the tint only the Color, It is possible that the color Magenta and Cyan are not completely matched, this is normal, the best is always only adjust the Color.
02.- Colors 75% For TVs with C.M.S. activated.
In some cases we can find TVs that have a Color Management System (C.M.S.), with this system we can adjust six colors individually Red, Green, Blue, Cyan, Magenta and Yellow, this system works to establish each color to its proper level but to do it properly it is necessary to use measuring equipment. Unfortunately the image of TVs that have this system looks very bad because, some colors are very saturated and Maintenance System Color can not turn off, but, when adjust each color to its proper level, the picture you have on screen, will be perfect.
Using Color Filters.
For this video pattern it is necessary to use color filters Blue, Red and Green or the TV can be set in Blue mode only, Red mode only or just Green mode only.
Each color bar has a level of 75% color to match it with the gray background, easily with color filters, or putting the TV in a color channel. The square between White and Black, and bars gradient between White and Black help us observe the color change produced by handling each color.
With color filters Blue, Red and Green, colors are set in this order.
Step 1. With Blue Filter or the TV in Blue mode only.
- 1.- The blue color is paired with gray background.
- 2.- Cian color is paired with gray background.
- 3. the Magenta bar is balanced with the Blue Bar.
Step 2. With Red Filter or TV in Red mode only.
- 1.- Yellow color is paired with gray background.
- 2.- Red bar is balanced with the Magenta bar.
Step 3. With Green Filter or TV in Green mode only.
- 1.- The green and yellow colors paired with gray background.
Gray gradients indicate the color change produced by handling each color. It is possible to adjust each color value, the color white and the color gradient between black and white they change color as the primary and secondary colors are adjusted, but once the process is complete, the white, and gray colors will have to see properly.
Using Measurement Equipment.
You need to use measuring equipment and accompanying software.
In this video pattern have a number of squares on the top and bottom ranging from White to Black in steps from 10 to 10. Then we have a degraded image White to Black, then we have a color bar representing the visible spectrum in the RGB color model. In the center of the image we have a gray background 75% of its value and 6 color bars 75% of its value.
Using a measuring equipment, increase or decrease each color until it is at 75% of its value Color.
To set each color to 75% of its value with measuring equipment and software, just check you get the following values. Here are the values of each color in different color models.
